<ul>
<li>alg - signature algorithm name (ex. {MD5,SHA1,SHA224,SHA256,SHA384,SHA512,RIPEMD160}with{RSA,ECDSA,DSA})</li>
<li>provider - currently 'cryptojs/jsrsa' only</li>
</ul>
<h4>SUPPORTED ALGORITHMS AND PROVIDERS</h4>
This Signature class supports following signature algorithm and provider names:
<ul>
<li>MD5withRSA - cryptojs/jsrsa</li>
